I LOVE terrariums. Not only do they require little effort to maintain but they are simple to make! I found the succulents, soil and rocks outside my house in Seattle and purchased the glass bowl/vase from World Market. You can find similar ones at Pottery Barn, Target, almost any glass bowl with work.
Step 1: Collect Materials- you can either buy at a planting store or gather outside your soil, succulents and rocks.
Step 2: Place rocks in your selected bowl. Enough to completely cover the bottom
Step 3: Then place potting soil over the rocks, about 6-8 inches.
Step 4: Plant succulents in the glass bowl make sure roots are fully covered and fill your bowl as little or as much as you would like!
Step 5: Sprinkle water over plants so all soil is moist
*Make sure to sprinkle water over plants every 3 days and if you place a lid on your plants keep an eye out for moisture. If you go to water your plant after 3 days and soil is still moist, wait a few days to water again.
Simple as that, now your house is more green.. until your plants die.. haha mine have been alive for 3 months so far, fingers crossed.
